Characterising englacial R-channels using artificial moulins
Journal of Glaciology, 2022 The englacial and subglacial drainage systems exert key controls on glacier dynamics. However, due to their inaccessibility, they are still only poorly understood and more detailed observations are important, particularly to validate and tune physical ...

Determining the evolution of an alpine glacier drainage system by solving inverse problems
Journal of Glaciology, 2021 Our understanding of the subglacial drainage system has improved markedly over the last decades due to field observations and numerical modelling. However, integrating data into increasingly complex numerical models remain challenging.

A novel approach to process brittle ice for continuous flow analysis of stable water isotopes
Journal of Glaciology, 2018 Brittle ice, which occurs in all intermediate-depth and deep ice cores retrieved from high-latitude regions, presents a challenge for high-resolution measurements of water isotopes, gases, ions and other quantities conducted with continuous flow analysis

New synthetic fiber armored cable for freezing-in thermal ice probes
Annals of Glaciology, 2021 A series of new synthetic armored cables were developed and tested to ensure that they were suitable for use with the RECoverable Autonomous Sonde (RECAS), which is a newly designed freezing-in thermal ice probe.
